# Section 0.1 - Requirements
- A **supported iOS device** (listed in the README)

- A **Linux install/live USB** or a supported **macOS** version
- The IPSW firmware for the version you want to downgrade to
- The script can download it for you
- The script will also provide a link to the IPSW if you want to download it manually
# Section 0.2 - Things to note before you begin
- **Windows:**
- **I recommend using iOS-OTA-Downgrader on Linux or macOS instead.** Windows SUCKS for anything downgrade or restore related.
- The Windows version of iOS-OTA-Downgrader will no longer be updated or supported.
- Read the ["Troubleshooting" wiki page](https://github.com/LukeZGD/iOS-OTA-Downgrader/wiki/Troubleshooting#windows) for more details about the stuff missing from the Windows version.
- **Windows/Linux**: Your installation must be **64-bit**, and x86_64. ARM is not supported.
- **Linux**: Your installation must be **64-bit**, and x86_64. ARM is not supported.
- **You do NOT need blobs to use this**, the script will get them for you.
- Some of the sections and steps will be separated depending on your platform and device.
- The restore will ERASE ALL DATA on your iOS device. Backup your data before proceeding.

# Section 1.1 - Setup for PC/Mac
## macOS/Linux
1. [Download iOS-OTA-Downgrader](https://api.github.com/repos/LukeZGD/iOS-OTA-Downgrader/zipball) and extract the zip archive.
- You may also clone the repo: `git clone --depth 1 git://github.com/LukeZGD/iOS-OTA-Downgrader.git`
1. Open a Terminal window.
- For macOS, [here's how](https://support.apple.com/guide/terminal/apd5265185d-f365-44cb-8b09-71a064a42125/mac)
- *macOS:** [Here's how (Open or quit Terminal on Mac)](https://support.apple.com/guide/terminal/apd5265185d-f365-44cb-8b09-71a064a42125/mac)
1. Go to where the extracted files are located, drag `restore.sh` to the Terminal window, and press Enter/Return.
1. On its first run, it will download and install dependencies. This will take some time depending on your Internet connection. When it's done, proceed to the next section.
## Windows
1. Install [iTunes](https://support.apple.com/kb/DL2065?viewlocale=en_US&locale=en_US), version 12.10.11 or newer. Make sure to not install the Microsoft Store version.
1. Install [MSYS2](https://www.msys2.org/#installation), follow steps 1 to 4 only. In step 4, untick "Run MSYS2 64-bit now" before clicking Finish.
1. [Download iOS-OTA-Downgrader](https://github.com/LukeZGD/iOS-OTA-Downgrader/archive/refs/heads/windows.zip) and extract the zip archive.
1. Go to where the extracted files are located, and run `restore.cmd`
- It may only show up as `restore`. If this is the case, run the one with the gears icon. I recommend to [make Windows show file extensions](https://www.howtogeek.com/205086/beginner-how-to-make-windows-show-file-extensions/) to avoid confusion.
